Abstract

See full text

An induced draft air-cooled condenser for steam condensing applications includes a pair of inclined tube bundles defining a interior space therebetween in fluid communication with ambient air heated as it flows through the tube bundles. A fan supported above the interior space comprises rotatable fan blades disposed inside a cylindrical annular fan shroud. A drive mechanism operable to rotate the fan blades includes a motor operably coupled to the fan blades. The motor is supported inside the fan shroud and may be housed in a protective enclosure which may be insulated. A motor cooling system includes an air inlet duct fluidly coupled to ambient air outside the shroud and the enclosure. When the fan operates, cool ambient air is drawn via a vacuum formed by the fan through the duct to cool the motor. The air thus bypasses and is not heated by the tube bundles.
